Strawberry plant named ‘DrisStrawOne’

ABSTRACT

This invention relates to a new and distinct cultivar of strawberry plant named ‘DrisStrawOne’. The new cultivar is primarily characterized by its relatively small plant size, medium fruit size and heavy fruit production.

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawOne’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivardesignated ‘DrisStrawOne’ botanically known as Fragaria×ananassa. Thisnew strawberry cultivar originated from a controlled cross between‘Driscoll El Capitan’ (U.S. Plant Pat. No. 14,005) and ‘Driscoll Agoura’(U.S. Plant Pat. No. 15,731). The original seedling of the new cultivarwas asexually propagated by stolons at a nursery in Shasta County,Calif. Propagules were transplanted to a controlled breeding plot inVentura County, Calif. where it was identified and selected for furtherevaluation in February, 2002. ‘DrisStrawOne’ was subsequently asexuallypropagated and underwent further testing at various locations in VenturaCounty, Calif. for four years. The present invention has been found toretain its distinctive characteristics through successive asexualpropagations.
